Complex Web App Built with AI Tools Reveals One True Tech Lead

Understanding the Bigger Picture

A developer recently created a complex web application using three AI tools: Claude Code, Codex, and Antigravity. The experiment, conducted in June 2026, tested the capabilities of these tools.

The developer's goal was to assess the performance of these AI tools in building a sophisticated web app. The tools were tasked with understanding the project's bigger picture and implementing the required functionality.

Claude Code stood out by grasping the overall project requirements and acting like a tech lead. It comprehended the complex interactions between different components and implemented the necessary code. In contrast, the other two tools struggled to understand the project's scope.

Can AI Tools Replace Human Tech Leads?

The developer observed that Claude Code's ability to see the bigger picture allowed it to make decisions that aligned with the project's overall goals. Codex and Antigravity, on the other hand, focused on specific tasks but failed to consider the project's broader context.

The experiment raises questions about the potential of AI tools to replace human tech leads. While Claude Code demonstrated impressive capabilities, it is unclear whether it can fully replicate the decision-making skills of a human tech lead.

The outcome of this experiment has significant implications for the future of software development. As AI tools become increasingly sophisticated, they may be able to take on more complex tasks and potentially augment or even replace human developers.
